Description of the invention (l) The present invention relates to the technology of multimedia playback ', and particularly to a playback method and device for dynamically adjusting frame output suitable for multiple systems. The current multimedia playback technology includes three major elements, namely the Multimedia Engine (Render Engine), the Multimedia Player (Play Back Engine) and the Multimedia Output Device (Dr aw Engine). The multimedia processor is used to process the original picture data, the multimedia player is used to control the playback rate, and the multimedia outputter is used to output the daytime data. Please refer to Figure i. The general execution flow is that the multimedia player 10 sends a day-to-day request to the multimedia processor 12 and then the multimedia processor 2 fetches the corresponding original day-and-day data from the file. Then, the multimedia processor 2 passes the obtained data from the beginning of the day to the multimedia player after passing through the data processing program. After taking it out, the multimedia player 10 passes the processed day-to-day data to the multimedia outputter 14 for output. I. Gray = In the process, when the multimedia player 10 sends-the picture to the bathroom, the middle + the multimedia output device 14 must wait, until the above-mentioned requirements are removed from the file, the second The day and night poor materials are processed by the multimedia processor 12 I, and after the processing is completed, they are passed back to Dora Dekui Cry in Dandan | by the multimedia player 丨 〇 Sample μ Xijun W 1 See, ° Xi Media Play Jie 1 0, The T-body output device 14 outputs the day-to-night media output device 14, and then the multi-media output device 14 often requires the execution of this single thread, which is a waste of multimedia.
